QA1 Adjustable Strut Rods

They are used Goodyear Assurance with a hard as rock treadwear rating. I bought the pair for $70 to get on the road without blowing a bunch more money right now. Obviously tires are at the used tire shop for a reason. It's not really a big problem for me. I may well be blaming the strut rods and Delrin for tire noise.
